Question

multiply and verify (xy + xy2 - 1) (2x + 3y)​

Answer 1

Answer:2x²y+2x²y²-2x +3xy²+3xy^4- 3y

Step-by-step explanation:

Answer 2

Answer:

2x²y+4x²y²-2x+9x²y-3y

Step-by-step explanation:

(xy+xy2-1) (2x +3y)

= 2x(xy+xy2-1) 3y(xy+xy2-1)

=[2x²y+2x²2y²4x-2x+3xy²+3xy²6y-3y]

=2x²y+4x²y-2x+9x²y-3y
